Description

  The present invention relates to a water discharge device, and more particularly, to a water discharge device that enables an automatic reciprocating operation that repeatedly changes a water discharge position such as a shower nozzle or a water spray nozzle.

  There is a growing need for shower systems and water discharge / spraying systems for relaxation and beauty and health promotion. In these applications, for example, there is an approach that promotes a massage effect or the like by modulating a water flow at a relatively high speed of several tens of hertz or more using a swirling flow or the like. On the other hand, for example, if the water discharge position and direction of the shower nozzle are repeatedly changed at a relatively slow speed of several hertz or less, for example, the water discharge is uniformly sprayed to a predetermined range of the human body to promote the relaxation effect, etc. Is possible.

  Similar needs exist widely in consumer equipment, industrial or agricultural applications, and require slow reciprocating motions for a variety of purposes such as cleaning, rinsing, cooling, humidification, pretreatment, and cultivation. It is said that.

  It is possible to use electric means such as motors and solenoids for reciprocal operation, but in order to install it in a system that discharges water in a bathroom, etc., measures for securing a power source, electric shock, and electric leakage are required. There are many problems to be solved in terms of cost and reliability.

  On the other hand, if the reciprocating operation can be realized by hydraulic power, electricity and lubricating oil are unnecessary, and improvement can be expected from many viewpoints such as initial cost, running cost, reliability, and maintainability. Therefore, the present inventors have developed a water discharge device that realizes a reciprocating operation by supplied hydraulic power and disclosed it in Patent Document 1.

  As shown in FIG. 1, in the water discharging apparatus 1 which concerns on this embodiment, the housing 2 whose external shape is a rectangular parallelepiped shape, for example is provided. The housing 2 is configured by closing an opening surface of a box-shaped housing body 3 whose one surface is open by a plate-shaped housing lid 4. A cylindrical water discharge cylinder 5 projects from the housing 2 on one side. The inside of the water discharge cylinder 5 has a hollow structure having a water discharge flow path 6, and the tip is opened. Further, water inlets 7 and 8 are formed in the housing body 3. The water inlets 7 and 8 are connected to, for example, branch ends of bifurcated water supply pipes (not shown), and fluids such as water or hot water are supplied at the same pressure. For example, the inner diameters and shapes of the water inlets 7 and 8 are the same as each other, and therefore the flow path resistances are also equal to each other.

Next, the internal structure of the housing 2 will be described.
As shown in FIGS. 2 to 4, a cylindrical cylinder space 10 is formed inside the housing 2, and a core 11 is placed in the space 10 in the center of the cylindrical space 10. It is accommodated so as to be movable along the axis. The core 11 reciprocates like a piston in the space 10 while dividing the space 10 into a pressure chamber 12 and a pressure chamber 13. Further, a water discharge cylinder 5 is connected to one side of the core 11. The central axis of the water discharge cylinder 5 coincides with the center axis of the core 11, and the water discharge cylinder 5 rises from the core 11, passes through the pressure chamber 12, passes through the housing body 3, and the housing 2 extends outside.

  Further, a core internal flow path 14 is formed in the core 11, and this core internal flow path 14 communicates with the water discharge flow path 6 in the water discharge cylinder 5, and the housing is formed via the water discharge flow path 6. 2 communicates with the outside. Furthermore, the water inlet 7 is in communication with the pressure chamber 12, and the water inlet 8 is in communication with the pressure chamber 13. Hereinafter, for convenience of explanation, the pressure chamber 12 side as viewed from the core 11, that is, the side where the water discharge cylinder 5 is provided is referred to as “left side”, and the pressure chamber 13 side, ie, the side where the housing lid 4 is provided. Is referred to as “right”.

  The core 11 includes a core body 16 in which a core internal flow path 14 is formed, and a core lid 17 connected to the core main body 16 so as to close the core internal flow path 14. Yes. A ring-shaped seal 18 is provided on the outer peripheral surface of the core body 16, i.e., the surface that slides with the inner wall of the housing body 3, for smooth sliding while maintaining liquid tightness. Further, a ring-shaped seal 19 is provided on the outer peripheral surface of the water discharge cylinder 5, that is, the surface sliding with the housing body 3 for the same purpose. As the material for the seals 18 and 19, for example, Teflon (registered trademark), NBR (nitrile rubber), EPDM (ethylene propylene rubber), POM (polyacetal), or the like can be used. Note that “liquid-tight” as used herein only needs to ensure a state sufficient to cause a pressure difference between the left and right pressure chambers.

Next, the internal structure of the core 11 will be described in more detail.
The core 11 is provided with introduction ports 21 and 22 for communicating the core internal flow path 14 with the pressure chambers 12 and 13, respectively. And the valve body 23 is provided so that the inlet 21, the internal channel 14 and the inlet 22 may be inserted. The valve body 23 is provided with a pair of main valve lids 24 and 25, and a main valve cylinder 26 that connects the main valve lid 24 and the main valve lid 25 to each other.

  As shown in FIGS. 5 and 6, the main valve lids 24 and 25 are each composed of a disc portion 27 and a cylindrical portion 28 connected to one side of the disc portion 27. A through hole 29 is formed along the central axis of the disk portion 27 and the cylindrical portion 28. On the other hand, the outer shape of the main valve cylinder 26 is substantially cylindrical, circular openings 30 and 31 are formed at both ends thereof, and a transverse opening 32 penetrating the center in a direction perpendicular to the central axis is formed. A plurality of ribs 33 extending in the axial direction of the main valve cylinder 26 are formed in a region excluding the opening of the transverse opening 32 on the side surface. The cylindrical portions 28 of the main valve lids 24 and 25 are fitted in the openings 30 and 31 of the main valve cylinder 26, respectively. Further, the groove portion between the ribs 33 is a fluid flow path in the introduction ports 21 and 22.

  A pair of bars 34 and 35 are attached to the valve body 23 so as to be movable with respect to the valve body 23. The bars 34 and 35 can move independently of each other, and the bars 34 and 35 constitute a slide bar. In this case, the bar 34 constitutes a portion of the slide bar on the pressure chamber 12 (see FIG. 4) side, and the bar 35 constitutes a portion of the slide bar on the pressure chamber 13 (see FIG. 4) side. Each of the bars 34 and 35 includes a cylindrical shaft portion 36 and a head 37 connected to one end of the shaft portion 36. The central axis of the shaft portion 36 coincides with the central axis of the head 37, and the diameter of the head 37 is larger than the diameter of the shaft portion 36. Accordingly, the shapes of the bars 34 and 35 are bowl-shaped. The shaft portions 36 of the bars 34 and 35 are inserted through the through holes 29 of the main valve lids 24 and 25, respectively, and the head 37 is disposed in the transverse opening 32 of the main valve cylinder 26. As a result, when the bars 34 and 35 are urged toward the main valve lids 24 and 25, the shaft portions 36 of the bars 34 and 35 slide in the through holes 29, and the head 37 is moved to the main valve lids 24 and 25. By engaging the cylindrical portion 28, the bars 34 and 35 press the main valve lids 24 and 25 from the inner side of the core 11 to the outer side, respectively.

  As shown in FIGS. 3 and 4, a leaf spring 40 is attached in the core inner flow path 14. The leaf spring 40 and the bars 34 and 35 constitute a control means. Both end portions of the leaf spring 40 are fixed to the core 11, and the central portion is inserted through the transverse opening 32 of the main valve cylinder 26 of the valve body 23. The leaf spring 40 is supported by the core body 16 in a state in which both ends thereof are pressed in a direction approaching each other, and the center portion thereof is curved so as to be convex on the left side and is convex on the right side. Two states of the curved state are stable states. When the leaf spring 40 is curved so as to protrude leftward, the central portion of the leaf spring 40 abuts against the head 37 of the left bar 34 and urges the bar 34 toward the left side. Thereby, the head 37 of the bar 34 presses the valve body 23 toward the left side. On the other hand, when the leaf spring 40 is curved so as to protrude rightward, the central portion of the leaf spring 40 abuts against the head 37 of the right bar 35 and biases the bar 35 toward the right side. Thereby, the head 37 of the bar 35 presses the valve body 23 toward the right side. In this way, the control means including the bars 34 and 35 and the leaf spring 40 presses the valve body 23 toward the left side from the inside of the core 11 (this state is hereinafter referred to as “leftward state”). A state in which the valve body 23 is pressed toward the right side from the inside of the core 11 (hereinafter, this state is referred to as a “rightward state”) can be selected.

Next, operation | movement of the water discharging apparatus which concerns on this embodiment comprised as mentioned above is demonstrated.
FIGS. 7A to 7D are schematic views illustrating the operation of the core of the water discharge device according to this embodiment.
First, as shown in FIG. 4, it is assumed that the core 11 is at an intermediate position in the moving range, and the leaf spring 40 is convex on the right side (pressure chamber 13 side). In this case, the central portion of the leaf spring 40 urges the bar 35 toward the right side, and the head 37 of the bar 35 is locked at the cylindrical portion 28 of the main valve lid 25. Thereby, it will be in the state (rightward state) which the bar 35 presses the valve body 23 toward the right side. As a result, the valve body 23 is located at the right end in the moving range, the disc portion 27 of the main valve lid 25 is separated from the core 11, and the disc portion 27 of the main valve lid 24 is separated from the core 11. In close contact. Thereby, the opening degree of the right inlet 22 is maximized, and the opening degree of the left inlet 21 is minimized. That is, the opening degree of the introduction port 22 is larger than the opening degree of the introduction port 21.

  In the present specification, the “opening degree” of the introduction port is a parameter that determines the flow path resistance of the fluid flowing through the introduction port. For example, in the state shown in FIG. 4, the channel resistance of the channel formed at the inlet 21 is higher than the channel resistance of the channel formed at the inlet 22. In this case, the opening degree of the introduction port 21 is smaller than the opening degree of the introduction port 22. The movement area of the core 11 refers to a space in which the core 11 actually moves when the water discharge device 1 is operated. Further, the end of the moving area refers to an end in the moving direction of the core 11.

  In this state, when a fluid such as water is supplied to the inlets 7 and 8 (see FIG. 3) at substantially the same pressure, the water introduced from the inlet 8 into the pressure chamber 13 flows into the core from the inlet 22. It flows into the channel 14 and flows out through the water discharge channel 6. On the other hand, the water introduced into the pressure chamber 12 from the water inlet 7 can hardly flow out because the inlet 21 is closed. For this reason, the pressure in the pressure chamber 12 becomes higher than the pressure in the pressure chamber 13, a rightward force acts on the core 11, and the core 11 moves to the right.

  When the core 11 moves to the right and reaches the vicinity of the end of the moving area, the shaft portion 36 of the bar 35 is moved to the inner wall of the pressure chamber 13, that is, the housing lid 4 as shown in FIG. Abut. Thereby, the bar 35 stops with respect to the housing 2. However, at this time, since the rightward force is still acting on the core 11, the core 11 continues to move toward the right side. As a result, as shown in FIG. 7B, the bar 35 moves to the left relative to the core 11. Thereby, the head 37 of the bar 35 presses the leaf spring 40 toward the left side, and the leaf spring 40 is in a neutral state.

  Thereafter, as shown in FIG. 7C, when the core 11 further moves to the right side, the bar 35 presses the leaf spring 40 further to the left side. As a result, at a certain point in time, the bending direction of the leaf spring 40 is reversed and becomes convex on the left side. Then, the central portion of the leaf spring 40 is separated from the bar 35 and comes into contact with the bar 34 and starts to urge it toward the left side. As a result, the head 37 of the bar 34 is engaged with the cylindrical portion 28 of the main valve lid 24 and the valve body 23 is pressed toward the left side (leftward state). As a result, the valve body 23 moves toward the left side with respect to the core 11, the disc portion 27 of the main valve lid 24 is separated from the core 11, and the disc portion 27 of the main valve lid 25 is separated from the core 11. Get closer to.

  When the valve body 23 reaches the center of the moving range, the opening degree of the introduction port 21 and the opening degree of the introduction port 22 become equal to each other, and a rightward force and a leftward force acting on the core 11 are generated. Will be equal. Thereby, the core 11 stops. However, at this time, since the valve body 23 is biased leftward by the action of the control means, the valve body 23 further moves to the left side, and the opening degree of the introduction port 21 becomes larger than the opening degree of the introduction port 22. . As a result, the pressure in the right pressure chamber 13 becomes higher than the pressure in the left pressure chamber 12, and a leftward force acts on the core 11. As a result, the core 11 starts to move toward the left side. Thus, the control means comprising the leaf spring 40 and the bars 34 and 35 switches from the “rightward state” to the “leftward state” when the core 11 reaches the right end in the moving range, The moving direction of the core 11 is reversed.

  As shown in FIG. 7D, when the valve element 23 reaches the left end of the moving range, the disc part 27 of the main valve lid 25 is brought into close contact with the core 11. Thereby, the opening degree of the introduction port 21 becomes the maximum, and the opening degree of the introduction port 22 becomes the minimum. As a result, the difference between the pressure in the pressure chamber 12 and the pressure in the pressure chamber 13 is maximized, and the leftward force acting on the core 11 is maximized.

  Thereafter, when the core 11 reaches the vicinity of the left end in the moving range, the bar 34 comes into contact with the inner wall of the pressure chamber 12, that is, the housing body 3. When the core 11 further moves to the left side, the bending direction of the leaf spring 40 is reversed by the same operation as the operation shown in FIGS. 7A to 7D, and the state of the control means is “leftward”. The state changes from “state” to “rightward state”. As a result, the moving direction of the core 11 is reversed. Thereafter, the core 11 reciprocates in the housing 2 by repeating the same operation.

Hereinafter, the effect of this embodiment will be described.
As described above, in the water discharge device according to the present embodiment, by supplying a fluid such as water or hot water to the water inlets 7 and 8, the fluid is discharged from the tip of the water discharge cylinder 5 while reciprocating the water discharge cylinder 5. Can be discharged. Therefore, if the housing 2 is fixed, it can be used as a water discharge device in which the water discharge position changes repeatedly. On the other hand, if the water discharge cylinder 5 is fixed, the housing 2 will repetitively move, and this movement can be used for massage, for example.

  In addition, according to the present embodiment, no mechanical power such as electricity is required, and smooth reciprocal reversal motion is possible only with the supply pressure of water (fluid), and there is no need for measures such as installation of a power source or electric shock or electric leakage. Become. In addition, smooth operation is possible without being affected by disturbances such as electromagnetic noise. As a result, it can be stably operated in various environments such as a bathroom, outdoors, or various industrial sites.

  Further, according to the present embodiment, since the heads 37 of the bars 34 and 35 are disposed in the transverse opening 32 of the main valve cylinder 26, the bars 34 and 35 (slide bars) connect the valve body 23 to the core 11. Press left and right from inside. As a result, the head 37 does not protrude outside the core 11, and the length of the portion of the bars 34 and 35 that protrudes outside the core 11 only needs to be the stroke of the bars 34 and 35. 11, the structure which consists of the valve body 23 and a slide bar can be formed compactly. As a result, the whole water discharging apparatus can be reduced in size.

  Furthermore, according to the present embodiment, the bar 34 and the bar 35 are separated from each other, and a connecting portion for connecting the two is not necessary. Therefore, the bars 34 and 35 can be formed thin. Thereby, the valve body 23 and the core 11 can be reduced in size, and as a result, the whole water discharging apparatus can be further reduced in size. Further, since the contact area between the bars 34 and 35 and the valve body 23 is reduced and the contact area between the valve body 23 and the core 11 is also reduced, friction between them can be reduced. Thereby, operation | movement of a water discharging apparatus becomes smooth and reliability improves.

  Furthermore, according to the present embodiment, since the bar 34 and the bar 35 are separated and can move independently of each other, only one of the bars 34 and 35 moves at a time. That is, when the core 11 reaches the left side (pressure chamber 12 side) of the moving area, only the bar 34 is pushed by the inner wall of the housing 2 and moves relative to the valve body 23, and the core 11 Reaches the right side (pressure chamber 13 side) of the moving area, only the bar 35 moves relative to the valve element 23. For this reason, compared with the case where the slide bars (bars 34 and 35) are integrally formed, the friction between the slide bar and the valve body 23 is halved. Furthermore, since the bar 34 and the bar 35 are separated, the center axis of each bar can be easily aligned, and the mass productivity is excellent.

  Furthermore, according to this embodiment, since the bar 34 and the bar 35 are formed as separate bodies and the leaf spring 40 is disposed between the bar 34 and the bar 35, the slide bar is inserted into the leaf spring 40. There is no need to form a through-hole. Thereby, since the intensity | strength of the leaf | plate spring 40 improves, while the reliability of the leaf | plate spring 40 can be improved, the leaf | plate spring 40 can be formed thinly and size reduction of a water discharging apparatus can be achieved.

  Furthermore, according to the present embodiment, the space 10 in the housing 2 has a substantially cylindrical shape, and a substantially disk-shaped core 11 is movably accommodated in the space 10. A water discharge cylinder 5 is provided along the axis, and the water discharge cylinder 5 is movable with respect to the housing 2. For this reason, the core 11 and the water discharge cylinder 5 can be freely rotated with their central axes as rotation axes. Thereby, when a shower head etc. are attached to the front-end | tip of the water discharge cylinder 5, the water discharge direction of this shower head can be selected freely.

  Thus, according to this embodiment, it is possible to realize a water discharge device that is small and highly reliable. Thereby, the freedom degree of installation of a water discharging apparatus improves, and it can install in the place where a narrow place or a maintenance is difficult.

  In addition, in this embodiment, although the example in which the water discharge cylinder was provided only in the one side of the housing was shown, the water discharge cylinder may be provided in the both sides of the housing. Moreover, in this embodiment, although the example which accommodated the disk shaped core in the substantially cylindrical space provided in the housing was shown, this invention is not limited to this. For example, the internal space of the housing may be a prismatic shape or a flat columnar shape, and the core can have various shapes according to these shapes. Furthermore, the outer peripheral shape of the water discharge cylinder need not be circular, but may be polygonal or flat. Furthermore, the water discharge cylinder need not be provided at the center of the core, but may be provided eccentric from the center of the core. If it does in this way, size reduction of a core is easy and a water discharging apparatus can be reduced in size.

  Furthermore, in the present embodiment, the leaf spring 40 as the urging means moves the bars 34 and 35 to the ends of their moving regions, that is, the main valve lids 24 and 25 have the opening ratio of the inlets 21 and 22. Although the example which presses to the position made into (10: 0) or (0:10) was shown, this invention is not limited to this. That is, the leaf spring 40 may urge the bars 34 and 35 to such an extent that a difference in opening degree is generated between the introduction port 21 and the introduction port 22, and then the valve body 23 moves due to the pressure difference between the pressure chambers. Thus, the opening degree difference between the introduction port 21 and the introduction port 22 becomes larger, and the same operation as in the present embodiment can be realized.

  Furthermore, in this embodiment, the bars 34 and 35 are brought into contact with the inner wall of the housing when the core is reversed, but the present invention is not limited to this. For example, a magnet is provided at the tip of the bars 34 and 35 and a magnet is also provided on the inner wall of the housing 2, and the bars 34 and 35 are moved relative to the housing 2 by utilizing the repulsive force acting between them. It can also be stopped. In this case, in a state corresponding to FIGS. 7A to 7C, the bar 35 does not contact the inner wall of the housing 2, and a predetermined force is applied from the inner wall of the housing 2 by the repulsive force of a magnet (not shown). It is in a state separated by a distance. In this way, the core can be reversed without contact. In this case, the moving range of the core is not a space where the core should have moved if there is no magnet, but a space where the core actually moves under the action of the magnet.

Next, a first modification of the present embodiment will be described.
FIG. 8 is a perspective view illustrating a valve body in the present modification.
As shown in FIG. 8, the valve element 41 in the present modification is configured by two main valves 42, and the main valves 42 are connected by two connecting rods 43. In each main valve 42, a cylindrical portion 44, a disk portion 45 having a diameter larger than that of the cylindrical portion 44, and a rib 46 formed on the outer peripheral surface of the cylindrical portion 44 are integrally formed. The central axis of the cylindrical portion 44 and the central axis of the disc portion 45 form the same straight line, and a through hole 47 is formed along the central axis, and the bar 34 or 35 is inserted into the through hole 47. is doing. The heads 37 of the bars 34 and 35 are disposed between the main valves 42. Moreover, the leaf | plate spring 40 (refer FIG. 4) is arrange | positioned so that it may pass between the connection rods 43 between the main valves 42. FIG. Configurations, operations, and effects other than those described above in the present modification are the same as those in the first embodiment described above.

  The main valves 42 may be connected not by the connecting rod 43 but by a screw (not shown), or extended from one main valve 42 and its tip engages with the other main valve 42. May be connected by a latch (not shown). The cylindrical portion 44 and the disc portion 45 may be assembled after being molded separately.

And a slide bar 53 inserted through the main valve lids 24 and 25. In the main valve carrier 52, ring-shaped holding portions 55 each of which is cut out are provided at both ends of a substantially strip-shaped substrate 54 extending in a direction from the main valve lid 24 toward the main valve lid 25. Ribs 56 are formed on the outer surfaces of the substrate 54 and the pair of holding portions 55. Further, the U-shaped member 57 is provided on the slide bar 53, and the insertion portions 58 are connected to both sides of the U-shaped member 57. The insertion portion 58 is a rod-like member extending in a direction away from the U-shaped member 57. A portion of the U-shaped member 57 on the pressure chamber 12 (see FIG. 4) side and a single insertion portion 58 connected to this portion constitute a portion of the slide bar 53 on the pressure chamber 12 side. The pressure chamber 13 side portion of the slide bar 53 is configured by the pressure chamber 13 (see FIG. 4) side portion of the shaped member 57 and the one insertion portion 58 connected to this portion.

  The outer surface of the cylindrical portion 28 of the main valve lids 24 and 25 and the inner surface of the holding portion 55 of the main valve carrier 52 are formed with mutually corresponding screws (not shown). The lids 24 and 25 and the main valve carrier 52 are connected. The main valve lids 24 and 25 and the main valve carrier 52 may be bonded. The insertion portion 58 of the slide bar 53 is slidably inserted into the through holes 29 of the main valve lids 24 and 25 while being slidably held by the holding portion 55 of the main valve carrier 52. Thereby, the slide bar 53 is movable relative to the main valve carrier 52 and the main valve lids 24 and 25. A leaf spring 40 (see FIG. 4) is inserted into the U-shaped member 57 of the slide bar 53.

  As shown in FIG. 9B, when assembling the valve body 51, first, the insertion portion 58 of the slide bar 53 is placed inside the pair of holding portions 55 in the main valve carrier 52. The slide bar 53 is incorporated into the main valve carrier 52 by inserting it through the notch. Next, the insertion portion 58 is inserted into the through hole 29 of the main valve lids 24 and 25, and the cylindrical portion 28 of the main valve lids 24 and 25 is screwed into and connected to the holding portion 55 of the main valve carrier 52. Thereby, as shown in FIG.9 (c), the valve body 51 is formed.

In the present modification, the leaf bar 40 (see FIG. 4) presses any pressure chamber side portion of the U-shaped portion 57, whereby the slide bar 53 is biased to either the left or right. When the slide bar 53 reaches the end of the moving range, the U-shaped member 57 contacts the holding portion 55 and presses the main valve lid 24 or 25 from the inside of the valve body 51 via the holding portion 55. . According to this modification, since the U-shaped member 57 is provided on the slide bar 53, it is possible to engage control means such as a leaf spring. Further, since the notch is formed in the holding portion 55, the integrated slide bar 53 can be incorporated into the holding portion 55. Configurations, operations, and effects other than those described above in the present modification are the same as those in the first embodiment described above.
In addition, in this modification, although the example which made the shape of the part which penetrates the leaf | plate spring in the slide bar 53 a U shape was shown, it is not limited to this. The shape of this portion may be, for example, a rectangular frame shape or an elliptical ring shape.

Next, a second embodiment of the present invention will be described.
FIGS. 10A to 10D are schematic views illustrating the operation of the core of the water discharge device according to this embodiment.
As shown to Fig.10 (a), in the water discharging apparatus which concerns on this embodiment, instead of a leaf | plate spring, the rotation lever 62 and the compression spring 63 are provided as an urging means which urges | biases a slide bar to right and left. ing. The pivot lever 62 is pivotable about the fulcrum 62a by pivotally supporting the fulcrum 62a provided at the central portion in the longitudinal direction thereof. Further, the upper end of the compression spring 63 is connected to the lower end of the rotation lever 62. A lower end portion of the compression spring 63 is supported by the core 11. Further, an extending portion 62 b extending in the rotation axis direction of the rotation lever 62 is provided at the upper end portion of the rotation lever 62. Then, when the turning lever 62 is turned, the extending portion 62b of the turning lever 62 comes into contact with the head 37 of the bar 34 or the head 37 of the bar 35 and urges them to the left and right. .

  The compression spring 63 is a “winding spring” in which a metal wire is formed in a spiral shape, and is used in a compressed state. When the upper end of the rotation lever 62 is located at both ends of the rotation area, the stress applied to the compression spring 63 is relatively small, and therefore the compression spring 63 has a small amount of compression and a low repulsive force. In this state, when the upper end of the rotation lever 62 is located at the center of the rotation area, the stress applied to the compression spring 63 is relatively large, and therefore the compression spring 63 has a large amount of compression. The amount of rebound is strong. Thereby, the urging means including the rotation lever 62 and the compression spring 63 selects a state in which the bar 34 is pressed to the left side and a state in which the bar 35 is pressed to the right side. Other configurations in the present embodiment are the same as those in the first embodiment.

Next, operation | movement of the water discharging apparatus which concerns on this embodiment comprised as mentioned above is demonstrated.
First, it is assumed that the core 11 is at an intermediate position in the moving range, the upper end portion of the rotation lever 62 is rotated to the right side, and the extending portion 62 b is in contact with the bar 35. In this case, the compression spring 63 urges the lower end portion of the rotation lever 62 upward, whereby the extension portion 62b of the rotation lever 62 urges the bar 35 toward the right side, and the bar 35 The valve body 23 is pressed toward the right side (rightward state). As a result, the valve element 23 is located at the right end in the moving range, the opening degree of the right inlet 22 is maximized, and the opening degree of the left inlet 21 is minimized. That is, the opening degree of the introduction port 22 is larger than the opening degree of the introduction port 21.

  In this state, when a fluid is supplied to the water inlets 7 and 8 (see FIG. 3), a pressure difference is generated between the left and right pressure chambers based on the same principle as in the first embodiment, and a rightward force is applied to the core 11. Works. As a result, the core 11 moves to the right and eventually reaches the vicinity of the end of the moving area.

  As a result, as shown in FIG. 10A, the bar 35 comes into contact with the inner wall of the housing 2 and stops with respect to the housing 2. However, at this time, since the rightward force is still acting on the core 11, the core 11 continues to move toward the right side. As a result, the bar 35 moves to the left relative to the core 11. Thereby, the bar 35 presses the extending portion 62b of the rotation lever 62 toward the left side, and the rotation lever 62 rotates counterclockwise as shown. At this time, the compression spring 63 resists this rotation.

  Then, as shown in FIG. 10B, when the rotation lever 62 rotates against the action of the compression spring 63 and the upper end of the rotation lever 62 reaches the center of the rotation area, the compression spring 63 rotates. The direction of the force applied to the lever 62 is the direction from the lower end of the rotation lever 62 toward the rotation center, and the compression spring 63 does not resist the rotation of the rotation lever 62. At this time, the compression amount of the compression spring 63 is maximized.

  Thereafter, as shown in FIG. 10C, when the core 11 further moves to the right side, the bar 35 further presses the extending portion 62b of the rotation lever 62 toward the left side, and the rotation lever 62 further counters. Rotate clockwise. As a result, the compression amount of the compression spring 63 exceeds the maximum value, and the counterclockwise rotation of the rotation lever 62 is promoted. Then, the extending part 62b of the turning lever 62 is separated from the bar 35 and comes into contact with the bar 34, and urges it toward the left side. Thereby, the bar 34 presses the valve body 23 toward the left side (leftward state). As a result, the valve body 23 moves toward the left side with respect to the core 11, and the opening degree of the introduction port 21 eventually becomes larger than the opening degree of the introduction port 22. As a result, a leftward force is applied to the core 11, and the core 11 begins to move toward the left side.

  Then, as shown in FIG. 10 (d), when the valve element 23 reaches the left end of the moving range, the disc part 27 of the main valve lid 25 is in close contact with the core 11. Thereby, the opening degree of the introduction port 21 becomes the maximum, and the opening degree of the introduction port 22 becomes the minimum. As a result, the pressure difference between the left and right pressure chambers is maximized, and the leftward force acting on the core 11 is maximized.

  Thereafter, when the core 11 reaches the vicinity of the left end in the moving range, the bar 34 comes into contact with the inner wall of the housing 2. When the core 11 further moves to the left side, the moving direction of the core 11 is reversed by the same operation as that shown in FIGS. 10 (a) to 10 (d). Thereafter, the core 11 reciprocates in the housing 2 by repeating the same operation. Operations other than those described above in the present embodiment are the same as those in the first embodiment described above.

  In this embodiment, since the deformation amount of the compression spring is small with respect to the displacement amount of the bar, the durability of the compression spring is high. For this reason, the reliability of the water discharging apparatus is high. The other effects in this embodiment are the same as those in the first embodiment.

  In the present embodiment, the shape of the turning lever 62 is an L shape in which the extending portion 62b extends from the upper end portion thereof, but the shape of the turning lever is not limited to this. For example, the portion where the compression spring 63 is connected at the lower end of the rotation lever 62 may be extended in the same direction as the extension 62b to form a C-shape as a whole, or the upper end may be provided without providing the extension. The part may be rounded to have an I shape. In the present embodiment, similarly to the first embodiment described above, the compression spring 63 as the urging means urges the bars 34 and 35 to a position where the opening degree difference between the inlets is maximized. Although an example is shown, the present invention is not limited to this, and the compression spring 63 may urge the bars 34 and 35 to a position where a certain degree of opening difference is generated between the left and right inlets. This is the same also about each modification of this embodiment mentioned below.

Next, a first modification of the present embodiment will be described.

Instead of the slide bar, an integrated slide bar 65 is provided. In the slide bar 65, an annular part 66 is provided at the center, and insertion parts 67 are provided on both sides of the annular part 66. The extension portion 62 b of the rotation lever 62 is located inside the annular portion 66 and is engaged with the annular portion 66. In this case, a portion on the one pressure chamber side in the annular portion 66, that is, a portion that abuts when the extending portion 62b of the rotation lever 62 is urged toward the one pressure chamber side, and a connection to this portion. This one insertion portion 67 constitutes the one pressure chamber side portion of the slide bar 65. The configuration other than the above in the present modification is the same as that of the second embodiment described above.

Next, a third modification of the present embodiment will be described.
FIG. 13 is a schematic view illustrating a valve body and a slide bar in the water discharger according to this modification.
As shown in FIG. 13, in the water discharging apparatus which concerns on this modification, compared with the water discharging apparatus which concerns on the above-mentioned 2nd Embodiment, the separation type which consists of bars 34 and 35 (refer Fig.10 (a)). Instead of the slide bar, an integrated slide bar 68 is provided. One surface of the center portion of the slide bar 68 is provided with a triangular convex portion 68a whose both side surfaces are smoothly inclined. The other surface of the center portion of the slide bar 68 has both side surfaces thereof. A rectangular convex portion 68b that stands vertically is provided. A guide 69 is provided inside the compression spring 63, and the expansion / contraction direction of the compression spring 63 is restricted to the direction toward the slide bar 68. Furthermore, a spherical body 70 is attached to the end of the compression spring 63 on the slide bar 68 side. The configuration other than the above in the present modification is the same as that of the second embodiment described above.

  In this modification, the compression spring 63 presses the spherical body 70 against the convex portion 68 a of the slide bar 68, so that the triangular convex portion 68 a converts the pressing force of the spherical body 70 into a horizontal force, and the slide bar 68. Is energized in either the left or right direction. Thereby, the rectangular convex part 68b of the slide bar 68 engages with the valve body 23, and the valve body 23 is urged | biased right and left. Operations and effects other than those described above in the present modification are the same as those in the second embodiment described above.

Next, a third embodiment of the present invention will be described.
FIG. 14 is a perspective view illustrating a water discharging device according to this embodiment.
FIG. 15 is a cross-sectional view illustrating this water discharge device,
16 is a cross-sectional view taken along line BB ′ shown in FIG.

  As shown in FIGS. 14 to 16, the water discharge device 71 according to this embodiment is provided with a housing 72. The housing 72 includes a cylindrical housing main body 73 having both ends opened, and plate-shaped housing lids 74 a and 74 b that close both ends of the housing main body 73. Further, from one side of the housing 72, that is, from the housing lid 74a, a cylindrical water discharge cylinder 75 extends in a direction perpendicular to the surface of the housing lid 74a. The water discharge cylinder 75 has a hollow structure having a water discharge channel 76 therein, and is open at the tip. Further, the housing body 73 is formed with two water inlets 77 and 78. For example, the water inlets 77 and 78 are respectively connected to branch ends of a bifurcated water supply pipe (not shown), and fluids such as water or hot water are supplied at the same pressure. For example, the inner diameters and shapes of the water inlets 77 and 78 are the same, and therefore the flow resistance is also the same.

Next, the internal structure of the housing 72 will be described.
A fan-shaped housing space 80 is formed inside the housing 72, and a core 81 is accommodated in the space 80 so as to be rotatable about the fan-shaped center of the space 80. The core 81 reciprocates while dividing the space 80 into a pressure chamber 82 and a pressure chamber 83. Further, a water discharge cylinder 75 is connected to the center of rotation of the core 81. Further, an inner core flow path 84 is formed in the core 81, and the inner core flow path 84 communicates with the water discharge flow path 76 in the water discharge cylinder 75 and communicates with the outside of the housing 72. Yes. Furthermore, the water inlet 77 is in communication with the pressure chamber 82, and the water inlet 78 is in communication with the pressure chamber 83.

  The core 81 includes a core main body 86 in which a core internal flow path 84 is formed, and a core lid 87 connected to the core main body 86 so as to close the core internal flow path 84. Yes. On the surface of the core body 86 that slides with the inner wall of the housing 82, a seal 88 is provided for smooth sliding while maintaining liquid tightness. A seal 89 is also provided on the surfaces of the housing lids 74a and 74b that slide with the water discharge cylinder 75 for the same purpose. As the material of the seals 88 and 89, for example, Teflon (registered trademark), NBR (nitrile rubber), EPDM (ethylene propylene rubber), POM (polyacetal), or the like can be used.

  The core 81 is provided with inlets 91 and 92 for communicating the core flow path 84 with the pressure chambers 82 and 83, respectively. And the valve body 23 is provided so that the inlet 91, the flow path 84 in a core, and the inlet 92 may be penetrated. Further, a pair of bars 34 and 35 are attached to the valve body 23 as slide bars. Further, a leaf spring 40 is provided between the bar 34 and the bar 35. The configurations of the valve body 23, the bars 34 and 35, and the leaf spring 40 are the same as those in the first embodiment.

Next, operation | movement of the water discharging apparatus which concerns on this embodiment is demonstrated.
Also in the water discharge device 71 according to the present embodiment, when the fluid is supplied to the water inlets 77 and 78 as in the first embodiment, the valve body 23 is controlled by the control means including the bars 34 and 35 and the leaf spring 40. Is biased toward one end of the moving area. Thereby, a pressure difference arises between the pressure chamber 82 and the pressure chamber 83, and the core 81 rotates. When the core 81 reaches the end of the rotation area, the state of the control means is switched, the direction of the force applied to the core 81 is reversed, and the rotation direction of the core 81 is reversed. By repeating this operation, the core 81 reciprocates in the space 80. Thereby, the fluid can be discharged from the tip of the water discharge cylinder 75 while rotating the water discharge cylinder 75 with the central axis as the rotation center.

In the present embodiment, in addition to the effects of the first embodiment described above, the following effects can be obtained.
17 (a) and 17 (b) are diagrams showing the effect of this embodiment. FIG. 17 (a) shows a state where the bar is in contact with the housing, and FIG. 17 (b) shows that the bar is pushed into the core. Indicates the state.
In the water discharge device 71 according to the present embodiment, the core 81 rotates within the housing 72. For this reason, the sliding direction of the bars 34 and 35 changes as the core 81 rotates. On the other hand, the bars 34 and 35 are slid by receiving a reaction force from the inner wall of the housing 72, and the direction of the reaction force is a direction perpendicular to the inner wall of the housing 72 and is therefore constant. For this reason, the core 81 rotates during the sliding of the bars 34 and 35, and the direction of the force applied to the bars 34 and 35 deviates from the sliding direction.

  That is, as shown in FIG. 17A, when the bar 34 comes into contact with the inner wall of the housing 72, the bar 34 slides on the bar 34 such that the longitudinal direction of the bar 34 is perpendicular to the inner wall of the housing 72. Even if the water discharger is designed so that a force N parallel to the direction is applied, as shown in FIG. 17 (b), when the bar 34 is pushed into the core 81, the core 81 is shown in FIG. Since it is rotated by an angle θ from the state shown in a), the sliding direction of the bar 34 is shifted by the angle θ with respect to the direction in which the force N is applied to the bar 34. On the other hand, even when the water discharger is designed so that a force in the sliding direction is applied to the bar 34 when the bar 34 is pushed into the core 81, the moment the bar 34 contacts the inner wall of the housing 72, The direction of the force and the sliding direction are shifted. Thus, in the water discharging apparatus of this embodiment, the direction of the force applied to the bar cannot always coincide with the sliding direction. When a force in a direction deviating from the sliding direction is applied to the bar, the bar hits the valve body and friction increases.

  On the other hand, in this embodiment, since the bar 34 and the bar 35 can slide independently of each other, the amount per piece can be reduced by half compared to the case where an integrated slide bar is provided. Thereby, a motion of a slide bar can be made smooth and the reliability of a water discharging apparatus can be improved. In this embodiment as well, a winding spring or a torsion spring may be used as the urging means, as in the second embodiment.

  In the above-described first to third embodiments and the modifications thereof, the end point for restricting the moving range of the core and inverting the core by operating the control means at the end of the restricted moving range. Adjustment means may be provided. Thereby, the reciprocating motion range of the water discharge cylinder can be adjusted, and the water discharge region can be controlled. As the end adjusting means, for example, a rod-like member that is attached so as to be insertable into the housing from the outside of the housing and is arranged at a position where the tip of the bar abuts when the core approaches is conceivable. The moving range of the core can be controlled by adjusting the insertion amount of the rod-shaped member.

  Moreover, in the above-described first to third embodiments and modifications thereof, a braking unit that brakes the movement of the core or the water discharge cylinder may be provided. Thereby, the movement speed of the water discharge cylinder can be controlled or stopped at an arbitrary position. As the braking means, for example, a blocking member that mechanically blocks the movement of the core or a sliding member that gives variable sliding resistance to the water discharge cylinder can be considered. Alternatively, a valve that stops the flow of fluid into at least one of the left and right pressure chambers may be provided, and a bypass that communicates between the left and right pressure chambers is provided, and an adjustment valve that makes the flow path resistance of the bypass variable is provided. May be. Also by these means, the speed of movement of the water discharge cylinder can be controlled by adjusting the force applied to the core.

  Furthermore, in the above-described first and second embodiments and modifications thereof, since the water discharge cylinder is bonded only to one side of the core, the surface of the core where the water discharge cylinder is bonded is opposite. The pressure receiving area is small compared to the side surface. Since the force that the core receives from the fluid is given by the product of the pressure receiving area and the fluid pressure, the maximum force that the core receives from the side with the water discharge cylinder (left side) is the side without the water discharge cylinder (right side) ) Is less than the maximum force received. For this reason, the speed at which the core moves to the right side is smaller than the speed at which the core moves to the left side.

  In the first and second embodiments, various effects can be obtained by utilizing the reciprocal speed difference. For example, when the water discharging device is used as a cleaning device, the cleaning efficiency can be improved by moving the water discharging cylinder slowly in the cleaning direction and quickly moving in the opposite direction to quickly return the water discharging position. Moreover, when using a water discharging apparatus for a shower massage apparatus, a massage effect can be heightened by moving a water discharging cylinder slowly in the direction which goes to a user's heart, and returning rapidly in the opposite direction.

  In addition, when the water discharge cylinder is joined to both sides of the core, there is no difference in pressure receiving area between both sides of the core. In addition, as in the third embodiment described above, even in the rotary water discharge device, there is no difference in pressure receiving area on both sides of the core. In these cases, the flow path resistance of the water inlets of the left and right pressure chambers or the flow path resistance of the pipes leading to these water inlets are different on the left and right, or the flow paths from the left and right pressure chambers to the core flow path By making the amount of leakage different from each other, a reciprocating speed difference can be made.

Next, a fourth embodiment of the present invention will be described.

In addition, the user does not have to change the site of action by shaking the body, which improves the feeling of use. Moreover, it is also possible to obtain a relaxation effect by applying spray-like water discharge over a wide range, and the usability is improved. On the other hand, when the water discharge nozzle 104 is fixed, the housing 2 moves, and this operation can be used for massage or the like. In other words, a massage effect such as “Momihoshi” can be obtained by pressing the body against the housing that moves left and right.
